As Drago said......................you really must report it if there was damage to a vehicle.
Some years ago I was involved in an incident where the other drive admitted fault. I didn't report it as my car was undamaged. He did report it and I got fined and the license endorsed simply for not reporting it.
I think you have 24 hours to do this (that part may have changed since my incident)
